During the last two weeks my raid5 array degraded while shutting down. Here's what happened at shutdown last time according to logs: Mar 29 05:16:27 xerxes shutdown[5690]: shutting down for system halt Mar 29 05:16:58 xerxes kernel: res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) Mar 29 05:16:58 xerxes kernel: ata3: soft resetting port Mar 29 05:17:03 xerxes kernel: ata3: port is slow to respond, please be patient (Status 0xd0) Mar 29 05:17:07 xerxes kernel: ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 310) Mar 29 05:17:37 xerxes kernel: ata3.00: qc timeout (cmd 0xec) Mar 29 05:17:37 xerxes kernel: ata3.00: failed to IDENTIFY (I/O error, err_mask=0x4) Mar 29 05:17:37 xerxes kernel: ata3: failed to recover some devices, retrying in 5 secs Mar 29 05:17:42 xerxes kernel: ata3: hard resetting port Mar 29 05:17:48 xerxes kernel: ata3: port is slow to respond, please be patient (Status 0xff) Mar 29 05:17:52 xerxes kernel: ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 310) Mar 29 05:17:52 xerxes kernel: ata3.00: failed to IDENTIFY (I/O error, err_mask=0x3) Mar 29 05:17:52 xerxes kernel: ata3.00: limiting speed to UDMA/100:PIO3 Mar 29 05:17:52 xerxes kernel: ata3: failed to recover some devices, retrying in 5 secs Mar 29 05:17:57 xerxes kernel: ata3: hard resetting port Mar 29 05:18:02 xerxes kernel: ata3: port is slow to respond, please be patient (Status 0xff) Mar 29 05:18:06 xerxes kernel: ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 310) Mar 29 05:18:06 xerxes kernel: ata3.00: failed to IDENTIFY (I/O error, err_mask=0x3) Mar 29 05:18:06 xerxes kernel: ata3.00: disabled Mar 29 05:18:07 xerxes kernel: ata3: EH complete Mar 29 05:18:07 xerxes kernel: sd 2:0:0:0: [sdb] Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK,SUGGEST_OK Mar 29 05:18:07 xerxes kernel: end_request: I/O error, dev sdb, sector 976751807 Mar 29 05:18:07 xerxes kernel: md: super_written gets error=-5, uptodate=0 Mar 29 05:18:07 xerxes kernel: RAID5 conf printout: What is this?
